Hello Friends,
Are you feeling boring today and want to play some game.What about if you play a game that was made be you !!! And it is made with only html5 and Jquery Then how about this ha.... (Really !!! Is it possible !!! ) absolutely why not . So get ready, today i will share a full source code with you. Just copy and paste it on plain notepad and save as [any name].html (format). After saving just open this *.html file with recent browser that support html5. don't worry recent all browser support html5. And most importantly you need latest jquery version to download.Click here to download latest jquery.So why we waiting for....
Here is the html source code below : (Just copy and Paste it)
